I'm using the latest version, 1.2.1, and I cannot find the option to turn it on.

It was working in a previous version, I think 1.1, but not anymore?

So far as I know there is no admin spam filter, so I think you have got some files out of place. Select one of the following spam filters as you desire:

none for minimal filtering
simple for some text processing
akismet or spamassassin if you have those services.

I reinstalled it and now it works. Sorry about that.

I'm donating some money for this awesome gallery. Thank you guys very much!

Can someone please tell me where the option to require moderation of comments should be found within the admin area? I would imagine it should be on the Options | Comment Configuration screen, but if it's there I don't recognize it as such.

I'm running ZenPhoto 1.2.2, and I've reinstalled and changed templates, but still cannot find this option.
Thanks,
Carol

There is not a simple answer. First you have to select a Spam filter. Then you can look at the options for the filter. The None filter gives you the option of reject, moderate, or pass. The other filters has the option of forgiving.

That works great - thank you!
